Abstract

An apparatus and method for cauterizing small vessels through small incisions or puncture openings is described. The apparatus is comprised of a pair of elongate electrodes capable of being inserted into a hollow needle. In a preferred embodiment, the elongate electrodes are disposed within a tube that is slidable in a longitudinal direction between a proximal position, in which the tube releases the electrodes into an outwardly biased position, and a distal position in which the electrodes are enclosed by the tube. The device is introduced into a body cavity with the tube in the distal position. The tube is then moved to its proximal position to release the electrodes, and a vessel is grasped using hooks at the electrode tips. A different electrical polarity is applied to each electrode, causing current to pass through the vessel from one electrode to the other to cauterize the vessel.
